WILLIAM C. PITTS, OF AUSTIN, TEXAS, ASSIGNOR TO WM. A. PITTS, OF SAMEPLACE.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 28,329, dated May 15,1860.

To all whom it may concern:

Be it known that I, WILLIAM 0. Plans, of thecity ofAustin, county ofTravis, in the State of Texas, have invented a new and useful machine,the same being a turning-plow; and I do hereby declare that thefollowing is a full, clear, and exact description of the constructionand operation of the same, reference being bad to the accompanyingdrawings, making a part of this specification, in Which- Figure 1represents a perspective view of the plow. Fig. 2 represents aperspective view from the land side of the plow, the landside beingremoved. Fig. 3 represents the inside of the mold-board. Fig. 4represents a perspective view taken from the rear and under side of theplow.

Similar letters of reference, where they occur in the several figures,denote like parts of the plow in all of them.

The nature of my invention consists in the manner in which I haveconstructed and arranged the mold-board and stock, so that themold-board may be turned on the stock and firmly held thereto by asingle bolt and the projection and recesses on the mold-board and stock,as will be explained.

To enable others skilled in the art to make and use myinvention, I willproceed to describe the same with reference to the drawings.

A represents the beam, B the handles, and (J the standard or stock, ofthe plow, which parts may be of wood, united or framed together in anyof the usual well'known ways.

D represents the mold-board, which has a concave face, is of atrapezoidal form, and has at two of its diagonal corners duck-billedpoints a a, and on its back two spur points or projections, c c. Thestandard is cut away, so as to leave afirm bearing for the mold-board,and

has also suitable recesses, e e, at opposite sides, one below, the otherabove, to receive the points 0 c. A single bolt, f, is then passedhorizontally or obliquely through the mold-board and the standard, andby a nut on the opposite side firmly (in conjunction with the spurs)holds the two together. When one of the points a becomes worn themold-board may be turned around and the other one put in use, the spursalso fitting into the recesses prepared for them.

E is the landside. It has a projecting piece on its upper side, which,together with the landside itself, is let into the stock or standardflush, and a bolt, 2', passes through this projecting piece and thestandard, and by a nut, n, on the other side firmly holds them together.The nut n may also take against the upper spur c to aid in holding it aswell as the mold-board to the standard.

on is a brace-rod extending through the beam and the standard, incliningbackward, so as to brace the standard to the beam.

Having thus fully described the object and construction of my plow, Iwould state that I am aware that reversible mold-boards have been used.This I do not claim irrespective of my particular construction of plow;but

What I do claim as new, and desire to secure by Letters Patent, is-- Theconstruction and arrangement of the mold-board and its 'points and spursand the standard with its concave bed and recesses for the purpose offorming a strong connection between the two and so that the mold-boardmay be turned or reversed thereon, as herein set forth and explained.
